The invention relates to tobacco pipes, and has among its objects the.provision of an improved removable tiltable cover therefor.

In tobacco pipes having resilient covers to permit springing apart ofthe arms that receive the bowl therebetween for release of the pivotalfastening means for removal of the cover, there is the ever presentdanger that the cover may be unduly strained or may be broken when theoperator forces the arms apart. This is particularly true if the coverbe made of Bakelite or other composition material, which is relativelybrittle or has very little elasticity.

Accordingly it is an object of the invention to provide means whichshall avoid this difiiculty and shall semi-automatically spring the armsapart to an exact predetermined degree.

Another, object of the invention is to provide improved mounting meansfor the cover to reliably hold the same against accidental tilting toopen position, even though the cover is otherwise mounted loosely andarranged with clearances for quantity production manufacture.

A further object of the invention is to provide such a cover with anauxiliary horizontal cover.

Other objects and advantages of the invention will become apparent asthe specification proceeds.

With the aforesaid objects in view,the invention consists in the novelcombinations and arrangements of parts hereinafter described in theirpreferred embodiments, pointed out in the subjoined claims, andillustrated in the annexed drawing, wherein like parts are designated bythe same reference characters throughout the several views.

In the drawing: 1

The advantages of the invention as here outlined are best realized whenall of its features and instrumentalities are combined in one and thesame structure, but, useful devices may be produced embodying less thanthe whole.

It will be obvious to those skilled in theart to which the inventionappertains, that the same may be incorporated in several differentconstructions. The accompanying drawing, therefore, is submitted merelyas showing the preferred exemplification of the invention.

Referring in detail to the drawing, l0 denotes a tobacco pipe embodyingthe invention. 'Ihe same may include a pipe bowl Ii having a stem. Forthe opening of the pipe bowl, there is provided a cover l3 comprising aperforated cover section M, undercut at its lower face l5, and having apair of depending spaced integral arms I 6. The latter receivetherebetween the bowl I I, and are shaped to fit the contour of thebowl, I

constructed as to prevent the cover from acci- :2"

dentally tilting from closed to open position, especially as suitableclearance must be allowed for in quantity production work, it beingdesirable to avoid expensive finishing operations.

Further, it is essential that in attaching and re moving the cover, theoperator shall not be called upon to force the arms apart and thus tomutilate or break the cover arms.

To realize these purposes, the head and socket means referred to maycomprise at each arm iii a plurality of spaced heads i0, i9 and a recesstherefor, the latter of which may include individual sockets for theheads. While the heads 18,

I9 may be provided on the arms and the sockets on the bowl, I prefer toform the heads in this instance on the bowl, and the correspondingsockets l8a, Isa, on the arms It.

Desirably the head 18 is eccentric to the cover and bowl, so that thecover may swing to lateral open position about the head E8. The head 18all) may be placed anywhere, but both of the heads ought to be disposednear the lower ends of the arms Hi to permit ample flexure of thelatter.

It will now be seen that when both heads l8, [9 are in engagement intheir respective sockets, accidental tilting of the cover to openposition is prevented. On forcibly moving the cover to the open positionshown, the head I!) disengages from its socket and rides along the flatface I! to cause the arms IE to spring apart for removal of the cover bymerely pulling the cover laterally from the bowl. To facilitate thedisengagement of the head IS the same may be suitably tapered or camshaped in order to slide out of its socket without breakage. It is notedthat the head [9 is substantially nearer to the end of the arm l6because the flexure there is greater than at the head I8, so that thehead I 9 may release without wholly releasing the head ill from itssocket. And yet a pull on the cover will suffice to fully disengage thethus partialy disengaged head 18. Hence the cover may remain pivotallymounted in its open position.

If desired, the head 13 may normally have a slightly greater depth ofengagement in its socket I811 than the head I9 has in its socket l9a toeifectively realize the purposes hereinabove stated. Since these headsare very small, being in the neighborhood of or in height, for Bakelite,it is not feasible to attempt to accurately show the shape andproportions of the different heads, but the description clearlyindicates the principles involved.

According to Figs. 6 and '7, a cover lSa is used, mounted like the coverl3 and being like the latter, except that it is formed in its topportion 20 with an opening 2| which forms a continuation of the pipebowl cavity and thus adds capacity to the pipe. An auxiliary perforatedcover disc 22 pivotally connected to the part 23 at 23 may behorizontally swingable to open and close the opening 2|. This provides adesirable variation to people who wish to have that type of cover, andprefer to have added bowl capacity when smoking in windy weather InFigs. 8, 9 and 10 is shown a fastening means which is similar inprinciple to that indicated at l8, I9. Here the cover I31) for the bowlIla may have a pair of heads 23, 24 at each arm "5a, with both headsextending along a horizontal line. A recess or socket shaped to receivethese heads is provided, comprising a groove 24a open at one end andterminating at its other end in a recess 23a, for their correspondingheads 24, 23. The operation is such as to prevent accidental tilting ofthe cover from closed position by reason of the engagement of the heads24 in the grooves 240. Further, the head 24, which is of slightly lessheight than the head 23, springs the arms lGa apart on tilting the coverto open position, to partially but not wholly, disengage the head 23. Onattaching the cover to a bowl, the heads 23, 24 enter and. ride in thegroove 24a until the heads 23 snap into their recesses 23a, the heads 24remaining in their grooves to act as stops. On tilting the cover theheads 24 are forced out of the grooves 24a and spring the arms apart forpartial release of the heads 23 from their recesses for easy removal ofthe cover. It is noted that whereas the head I9 is at a differentelevation than the head l8 so as not to accidentally snap into thesocket lBa, such an occurrence cannot take place with the elements 23,24 which may accordingly be horizontally arranged.

The provision of the groove 2411 results in certain distinct advantages,in that it permits the pivotal heads 23 to be made relatively large andrugged, without necessitating an undue springing apart of the coverarms, and nevertheless permits a large depth of engagement in theirrecesses 23a in the vertical direction to reliably holdthe cover in itsclosed position. Such substantial engagement occurs also even when theheads 24 spring the cover arms apart in the open position.-

Moreover, the attachment of the cover to the pipe bowl is simplifiedsince the cover arms are initially sprung apart only by the heads 23which easily enter the grooves.

It is thus seen that the invention fulfills the objects stated and isinexpensive in manufacture and reliable in use, and permits the cover tobe easily removed for cleaning or replacement by a cover of anotherconstruction or design.
